The LG (BT ULL) ultra low latency Bluetooth technology has been used first for a gaming controller developed by Razer

LG Electronics (LG) has collaborated with Razer and MediaTek to introduce the world’s first Bluetooth Ultra-Low Latency (BT ULL) Controller at LG webOS Summit 2024 on September 27.

This groundbreaking technology was showcased through an LG webOS smart TV and Razer’s Bluetooth gaming controller, demonstrating the game-changing 1 ms input lag.

The webOS summit, which welcomed 300 representatives from 140 partner companies – including content developers, producers and providers – from 24 countries, shared LG’s strategic vision and future initiatives for expanding its AI webOS ecosystem and platform business.

Razer, a leading global lifestyle brand for gamers, has developed the first game controller featuring BT ULL technology. To showcase its upgraded performance, LG and Razer compared a BT ULL-enabled Bluetooth game controller to a standard controller during the event.

 

The demonstration highlighted the superior responsiveness, reduced input lag and control precision of the BT ULL technology across various cloud-based games, including FPS, fighting and racing titles.

 

The latest BT ULL technology offers the perfect cloud gaming performance, catering to competitive players who require lightning-fast response times to excel in their games.

In an industry first, LG plans to introduce a certification program for third-party game controllers in the near future to ensure BT ULL-supported controllers work seamlessly with LG webOS smart TVs.

Razer will be the first company to obtain LG’s certification.

Meanwhile, LG and MediaTek, a global fabless semiconductor company, are jointly developing the BT ULL technology to be integrated into MediaTek’s Wi-Fi “MT7921” chipset.

This chipset will also feature the efficient and reliable Wi-Fi 6 technology from MediaTek’s Filogic series.

These collaborative efforts aim to enable LG webOS smart TVs owners to immediately dive into online multiplayer cloud games with the enhanced response times, delivering unprecedented levels of realism during gameplay.

The latest premium LG OLED TVs and LG QNED TVs, supporting refresh rates of 120 Hz or higher, are scheduled to launch in 2025 with BT ULL technology.

“LG is committed to consistently introducing more advanced features designed to immerse gamers in their favorite titles and to differentiate its gaming experiences,” said Baik Seon-pill, head of the LG Home Entertainment Company’s Product Planning Division.

“As the LG webOS platform evolves, so will the features that make it the ultimate gaming platform for every type of gamer.”

Bluetooth is getting a huge upgrade for gamers — ultra-low 20ms latency

Qualcomm wants to give gamers a nearly latency-free experience with its upcoming S3 Gen 2 Sound platform that runs on Bluetooth 5.4. The platform, which was just announced today (June 23), promises sub-20ms latency that’s far below the 100ms latency of Bluetooth 5.3. 

The S3 Gen 2 Sound platform builds on Qualcomm’s work with aptX Low Lantecy, a codec that delivers audio with just a 40ms delay. The S3 Gen 2 platform will cut that time in half.

Why do you want faster delivery over Bluetooth? Well, for gamers, it’s all about hearing your teammates in real-time, which is incredibly important for games like Call of Duty Mobile.

There are, of course, some caveats to this. 

Gaming controllers

The controller could significantly reduce the input lag for cloud-based gaming. BT ULL is currently an in-development standard for gaming controllers that intends to make wireless controllers “responsive as USB-wired or proprietary wireless communications.”

During the event, LG compared their prototype against a “standard controller.” We can’t tell precisely what the standard controller is from images provided by LG, but it appears to be a third-party wireless Bluetooth controller.
